Step-by-step explanation:
48000 = 40000(1+r/100)^2 ( The formula is a(1+r/100)^n
(1+r/100)^2 = 484/400
(1+r/100)^2 = (22/20)^2
1 + r/100 = 22/20
r/100 = 22/20 - 1
= 1/10
r = 100/10
= 10.
The rate of growth per annum = 10%.

Step-by-step explanation:
Total increase in production in two year=48400-40000=8400
As growth rate is same during the two years then per year increase in production=(8400/2)=4200
growth per annum
={(44200-40000)/40000}★100=10.5%
